We present here a systematic study of dynamic behavior for polymer (PE) melt by means of Dissipative Particle Dynamics (DPD). We used DPD spring potential between adjacent segments. By changing various parameters related to spring potential like stiffness k, equilibrium distance r0 and parameters related to dynamic behavior like friction coefficient γ presented in dissipation force we tested their influence on scaling laws. We also compared these scaling laws obtained from our simulations with predictions from Rouse theory.
